uR type fusewith or without striker
High-speed fuses (uR)gR and aR curvesfrom 5 to 2000 A
Function
Advantages
High speed fuses (uR) protect power semiconductors and DC circuits.
High level performance • Very high breaking capacity up to 300 kA. • Very high limitation of short-circuit currents (and therefore significant reduction in thermal and mechanical stress).
• Good resistance to cyclic loads.
High reliability • Absolute protection over time guaranteed by the simplicity of manufacture and function (Joule effect).
• No downgrading of fuse characteristics over time.
Improved safetyThe energy released whilst eliminating the fault (fuse blowing) is contained within the cartridge (no degassing).
Fuse blown indicatorAn auxiliary contact can be adapted to signal that a fuse has operated.
